This Essay is after watching the video and reading 4 articles plus chapter3 we need to define momentum and inertia and explains the importance of wearing seat belts while riding in an automobile. The video was about what happens to a person when he/she is in a situation in a car accident, what will happen to the passenger and the other people in the back seat? What will happen to the car after the crash? Will the people survive or die? There are many questions to answer in this essay.
Body of Essay:
The force on an object is equal to mass divided by velocity. In the video we saw how the car gets into a wall without paying attention, many people passed away because of texting while driving or not paying attention while trying to answer a call. Other people die because they’re not wearing seatbelts and they die. In 2009 there were 33,808 people died in traffic crashes in the United States, including an estimated 10,839 people who died in alcohol-impaired driving crashes. Newton’s first law of motion stated that every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. This concept is known as inertia. If a car is in motion and hits a brick wall, the passenger will remain in motion until stopped by an external force, like the brick wall. If the passenger is wearing a seatbelt, the seatbelt will be the external force that keeps the passenger from remaining in motion. Another thing is Things take time to slow down.
The Essay on Methods Of Euthanasia People Die Life
Intentionally making someone die, rather than allowing that person to die naturally is the definition of euthanasia according to the International Anti-Euthanasia Task Force (Euthanasia: Answer to Frequently Asked Questions, 1). This definition, itself, does not sound very appealing. The practice of euthanasia in any shape or form should never be legalized in the United States and should be banned ...
When a cannonball lands, it takes time to decelerate, transferring its energy to its target. Its velocity does not instantaneously go to zero; otherwise, it wouldn’t cause so much damage. Newton’s Second law of motion stated that the relationship between an object’s mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors; in this law the direction of the “force vector” is the same as the direction of the “acceleration vector.”. an example of this law is the amount of force needed to move a 1,000kg object at 5 meters per second is 5,000 Newton’s. Another example is when dropping a handful of Play-doh on a turntable makes it slow down because the rate of change of mass went up. For constant F, “a” must go down if “m” goes up Newton’s Third law of motion states that For every action there is an equal and opposite reaction.
An example of Newton’s Third law of motion would be when a fish and birds move by pushing their surroundings (water and air) behind them, which propels them forward. Another example would be when two skaters pushing each other away exert the same, but opposite, force on each other. One can’t push the other away without himself being forced away. All of those laws were invented by Isaac Newton. He was the first scholar to invent the motions and forces laws. He was famous for inventing the three laws of motion and mathematic equations. So now all the answer to all of these questions is that it depends on the car accident. Some people can get injured and some of them survive. There are some of the car accidents when the cars flips and go down the hill and this type of accident 90% of chance people will die, but 1% is the chance of people who will survive.
Conclusion:
This essay was suppose to describe the three laws of motion and forces formulas and also answer some of the questions. All three laws came after each other and they all were related. The meaning of this essay is suppose to explain the safety of wearing a seatbelt and what are the dangerous things that might happen to you when you are not wearing it. If you do not wear a seatbelt and you get in a car accident it can lead to injuries or deaths. I think that we all should wear seatbelts and try not to speed up to 100mph just trying to get to school, and school is like 5 minutes away from your house. My advice to everyone is to wear seatbelts and try not to speed up.
The Essay on E104 Newton’s Second Law of Motion
The experiment that was conducted was primarily about Newton’s second law of motion. Newton’s second law of motion states that a net force is required for a body to have acceleration. If a net force is applied on an object, then the object will accelerate with respect to the direction of the said force. The body’s acceleration is directly proportional to the net force and inversely proportional to ...
